If any of you are running the arm free beta, there was a great change in the 222 sdk which I think is awesome - I was a big advocate for the change! - but which means the 222 sdk makes an arm plugin with different names than 221.
So short version: if you use the surge arm beta it now uses the 222 sdk and so you need 222 free
And plugins built with 221 that haven’t updated yet may not load properly. If they don’t just rename plugin.Dylib to plugin-arm64.dylib
(This change means you can have a rack user directory with both arm and x64 plugins in one spot which is super operationally useful and I’m thankful for vortico and team for adding it)
